The NGK B6HS-10 Spark Plug (MPN: 1052) is an essential ignition component designed for specific outboard marine engines, including Yamaha 3Hp and select Suzuki DT-series models. It offers reliable cold-starting performance and consistent combustion stability, though users must strictly verify compatibility with their specific engine manual to ensure the correct heat range and thread specifications.

This plug requires a 20.8mm spanner/socket.
The B6HS-10 is typically specified for 2-stroke outboard applications; check your owner's manual before use.
Compare the thread length (12.7mm) and outer thread diameter (14mm) against your current plug specifications.
Only a very small amount is recommended, as excess can affect torque readings and grounding.
It is best practice to replace them annually or every 100 operating hours to maintain optimal performance.
Verify the spark plug wire is fully seated and check the spark plug for fuel fouling or carbon buildup.
Check the gap of the electrode and ensure the plug is not cracked or damaged; replace if the insulator is chipped.
When installing the NGK B6HS-10, always use a spark plug socket with a 20.8mm hex. Hand-thread the plug first to avoid cross-threading the aluminum cylinder head, then tighten to the manufacturer's specified torque.
